An eyebrow-raising video of Meghan Markle and Prince Harry during the 2019 event shows the Prince instructing his wife on royal protocol.

During Trooping the Colour 2019, Meghan Markle was observed having a brief and seemingly tense exchange with Prince Harry on the Buckingham Palace balcony while celebration events took place for the late Queen Elizabeth II’s birthday.

It appears that Prince Harry was reminding his wife of the upcoming anthem to ensure she was prepared and facing the right direction by telling her to “turn around” twice, when she tried to turn her back on the crowds below. For Harry, maintaining protocol and smooth public appearances were taught from a young age.

The video gained huge traction on social media and has recently resurfaced as the Royal Family prepares for Trooping the Colour 2024 to mark King Charles’s official birthday on Saturday, June 15.

Footage shows the Sussexes are on the balcony during Trooping the Colour 2019 and Meghan Markle could be seen turning around to chat with her husband, just before the National Anthem was played.

As the National Anthem began playing Harry could be seen telling Meghan to “turn around” when she tried to engage with her husband and initiate a conversation.

The Duchess appeared to look quite upset when this interaction happened but much has been read into the interaction over the years, with some saying Harry was merely trying to look out for his wife, who may have been unaccustomed to the protocol.

Judi James, a professional body language expert, spoke exclusively to Express.co.uk at the time to explain how Meghan may have been feeling at this moment.

She said: “It’s easy to forget how much pressure Meghan might have felt herself to be under, coming from the US which has no Royal Family, and immersing herself in both her husband’s family and the more formal side of his lifestyle.

“So events like the Trooping of the Colour might have even come as a bit of a shock to a woman who claims to have initially had little knowledge of skills like the curtsey.”

Judi added: “Her [Meghan Markle’s] blink rate does seem to have speeded though, which is a gesture that can hint at either some upset or irritation.”

The Duchess of Sussex’s second appearance at Trooping the Colour was her first public appearance since the birth of her son Archie, attending the late Queen’s birthday parade alongside the rest of the Royal Family.

As they are no longer working royals, Meghan and Harry will not be attending Trooping the Colour this year. The King’s Birthday Parade, scheduled for Saturday, June 15, will kick off at 10:20am.

Charles’s actual birthday is on November 14, but it is tradition for the reigning monarch to have an unofficial birthday in June, so the entire nation can join in the celebration.

One royal commentator, Kinsey Schofield, believes the couple might decide to choose the day to hit headlines so they are not sidelined. Ms Schofield, To Di For Daily host, said: “I would not be surprised if we saw American Rivera Orchard launch a product around Trooping the Colour.”

Meghan first launched her lifestyle brand on March 14, but there has since been a lull in brand activity. She then resurfaced at the end of April, giving out handmade jams to 50 friends and influencers to share via social media.
